Our software uses PCommServer to talk to the TurboPMAC card. We have noticed that since the latest Windows 10 update (Version 1709, build 16299.125) we seem to get a lot of hanging when trying to communicate with PMAC.

While this is happening, PeWin also hangs. I have to kill the instance of PCommServer and pull out the USB plug to get it working again.

I guess you might suggest that it is our application, but we have not seen this before the latest Windows 10 release.

As an aside, we also needed to re-install the driver and insert the device when this Windows 10 version came along.
